No god role playing
You cannot control another players character or monster. The only time and place that this would be allowed is during giant monster battles, but that's only after the player you have been battling hasn't posted in three days.
No killing of other players characters unless the other player allows it
In this case, the killed character/monster cannot return.
Don't time travel
This RPG revolves around the real world clock. Seasons will change the do in the real world and there will be holidays/festivals to reflect that.
Multiple characters
You are allowed to have up to three characters of any race.
Giant Monster attacks have no impact of everyday living in a populated area
Battles that are scheduled to take place in any populated area are acted independently from the human side of things outside of the story.
You are not limited to being a human character
If you want to be a Furry, fine. How about a Locust(Gears of War)? Or what about a Furry that has the ability to turn into a human? It's all good as long as you're not some fifteen foot tall being.
Try to be realistic
If you're role playing with someone in one area, you are not allowed to suddenly jump to another area and suddenly be talking to a completely different character.
